The main problem with the stock intake is not the size of the runners, but the length and shape of them. Factory manifolds are designed for good drivability and emissions at all rpms. So even if you could port it you wouldn't notice much. I recently picked up a used typhoon on ebay for $400 and spent 2 hours porting and polishing it. Should make some nice HP for not a lot of money.

Well I found this after I asked the question:

http://www.musclemustangfastfords.co...bullittintake/Bullitt Blast Performance enthusiasts know one way to increase power is to improve the airflow to the engine. If you own a 4.6 2V, it means installing an '01 Bullitt intake manifold. Unlike the plastic intakes found on all '96-present GT models, the '01 Bullitt manifold is cast aluminum which gives it some advantages--first, because it can be ported, and second, because if you run nitrous, there is a much smaller chance of blowing the thing into a million pieces should your engine encounter a dreaded nitrous backfire. Another attribute is the shorter, yet larger, runners. If there is a downside, it is the weight. The Bullitt intake weighs about 35 pounds, which is about twice the weight of the plastic one.

Hell, I port matched my stock (plastic PI) intake with some router bits made for wood just to even up the entry into the ported heads. I don't know if it really mad a difference, but it inly took about 30 minutes. Just be careful not to get in there to deep. That plastic comes off fast.
